First-Aid Measures
Description of first aid measures

General advice:
Remove contaminated clothing.

If inhaled:
Keep patient calm, remove to fresh air, seek medical attention.
Immediately administer a corticosteroid from a controlled/metered dose inhaler.

If on skin:
Wash thoroughly with soap and water.
If symptoms persist, seek medical advice.

If in eyes:
Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open, consult an eye specialist.

If swallowed:
Immediately rinse mouth and then drink 200-300 ml of water, seek medical attention.

Fire-Fighting Measures

Extinguishing media
Suitable extinguishing media: water spray, dry powder, foam

Special hazards arising from the substance or mixture
Hazards during fire-fighting: harmful vapours, carbon oxides
Evolution of fumes/fog. The substances/groups of substances mentioned can be released in case of
fire.

Advice for fire-fighters
Protective equipment for fire-fighting: Firefighters should be equipped with self-contained breathing apparatus and turn-out gear.

Further information:
The degree of risk is governed by the burning substance and the fire conditions.
Contaminated extinguishing water must be disposed of in accordance with official regulations.

Handling

Precautions for safe handling
No special measures necessary provided product is used correctly.

Conditions for safe storage, including any incompatibilities
Suitable materials for containers: High density polyethylene (HDPE), Low density polyethylene (LDPE), Stainless steel 1.4301 (V2), Stainless steel 1.4306 (V2A), Stainless steel 1.4361, Stainless steel 1.4401, Stainless steel 1.4439, Stainless steel 1.4539, Stainless steel 1.4541, Stainless steel 1.4571, Stove-lacquer RDL 50
Further information on storage conditions: Keep container tightly closed and dry; store in a cool
place.

The packed Dehydol LT 7 is not damaged by low temperatures or by frost.
Bulk must be protected from solidification.

Protect from temperatures above: 70 °C

Properties of Dehydol LT 7 change irreversibly on exceeding the limit temperature.

STORAGE

a) Dehydol LT 7 should be stored indoors in a dry place. Storage rooms must not be overheated (see flash point).

b) Dehydol LT 7 is hygroscopic due to its good solubility in water, with the result that it may absorb moisture very quickly.
Drums must be resealed each time they are opened.

c) The storage temperature should not be allowed to fall substantially below 20 °C.
The congealing point of Dehydol LT 7also need to be taken into account.

d) Dehydol LT 7 is a cloudy liquid and tend to form sediment, it becomes clear liquid at 40 °C.

e) Liquid that has solidified or that shows signs of sedimentation should be heated to 50 – 70 °C and homogenized before it is processed.
Please mix sufficiently prior to use.

f) Drums that have solidified or that have begun to precipitate should be reconstituted by gentle heating, preferably in a heating cabinet.
The temperature must not be allowed to exceed 70 °C.
Please mix sufficiently prior to use.
This also applies if drums are heated by external electrical elements.
Internal electrical elements should not be used because of the localized anomalies in temperature that they cause.

g) Dehydol LT 7 must be blanketed with nitrogen if they are stored in heated tanks (at 50 – 60 °C) to prevent it from coming into contact with air.
Constant, gentle stirring helps to prevent it being discolored as a result of prolonged contact with electrical elements or external heating coils.
